GBA enforcement

Handhaving in Belgium
The Belgian GBA's 2022 ruling against IAB Europe — fining them €250,000 for the Transparency and Consent Framework — sent shockwaves through the entire EU ad-tech industry. The GBA has also fined a Belgian company €50,000 for sending marketing emails without valid consent, and regularly publishes enforcement decisions to increase awareness.
